a study to evaluate the benefit of adding durvalumab after chemotherapy, durvalumab and surgery in patients with early-stage, operable, non-small cell lung cancer.

Conditions: Non Small Cell Lung Cancer

Summary: adopt-lung is an international, multicentre, open-label randomised phase iii trial. protocol treatment consists of 3-4 cycles of neoadjuvant durvalumab in combination with platinum-based doublet chemotherapy, followed by surgery. patients with r0 and r1 only resection will be randomised to receive either adjuvant durvalumab for 12 cycles (experimental arm) or observation (control arm). the primary objective of the study is to determine whether additional adjuvant immunotherapy with durvalumab after neoadjuvant chemo-immunotherapy has an effect on disease-free survival (dfs) in patients who do not achieve complete pathological response (pcr) as per local assessment according to the iaslc recommendations.


Eligibility criteria:
inclusion criteria for enrolment: * histologically confirmed nsclc. * stage iib-iiib (t1-4 n0-2) according to 8th edition of the tnm staging system of lung cancer. stage iii assessment should include samples of lymph nodes at levels 4, bilaterally, and level 7 to rule out stage iiib n3 disease. t4 tumours will only be eligible if they are defined as t4 based only on their size (\>7cm); any other reason will be considered ineligible. * known pd-l1 status, as tested locally using a validated assay. to ensure comparability of results, it is strongly encouraged that pd-l1 testing is done with the ventana pd-l1 (sp263) assay. * absence of egfr mutation or alk translocation, as tested locally. * primary tumour resectable and functionally operable as assessed per local multidisciplinary tumour board (cardiac evaluation, pulmonary function and diffusion capacity, comorbidity). * adequate haematological function: haemoglobin ≥90 g/l, absolute neutrophil count (anc) ≥1.0× 109/l, platelet count ≥75× 109/l. - adequate renal function: measured creatinine clearance (cl) \>40 ml/min or calculated cl \>40 ml/min calculated by the cockcroft-gault. - adequate liver function: alt and ast ≤2.5× institutional uln, total serum bilirubin ≤1.5× institutional uln (patients with gilbert's syndrome may be allowed to be enrolled after consultation with the medical affairs team at the etop ibcsg partners foundation. * eastern cooperative oncology group (ecog) performance status 0-1. * age ≥18 at the time of enrolment. * body weight \>30 kg. * life expectancy of at least 12 weeks. * women of childbearing potential, including women who had their last menstruation in the last 2 years, must have a negative urinary or serum pregnancy test at screening before enrolment. pregnancy test must be repeated within 3 days before the first dose of protocol treatment. * written ic for study participation must be signed and dated by the patient and the investigator prior to any study-related intervention. eligibility criteria for randomisation: * surgical resection must have been completed. note: participants who have had only had segmentectomy or wedge resections are not eligible for randomisation. * patients must have complete resection: r0 or r1 resection. * patients must be fit to receive adjuvant treatment with durvalumab. * patients must have no evidence of metastatic disease as assessed by ct scan. * documentation of pathological response as per local review must be available. exclusion criteria for enrolment: * t4 with invasion of heart, great vessels, carina, trachea, oesophagus, or spine. * any previous or concurrent treatments for nsclc. * any previous immunotherapy. * major surgical procedure (as per investigators assessment) within 28 days before enrolment. * history of allogenic organ transplantation. * active or prior documented autoimmune disease or inflammatory disorders (including inflammatory bowel disease \[e.g., colitis or crohn's disease\], systemic lupus erythematosus, sarcoidosis syndrome, or wegener syndrome \[granulomatosis with polyangiitis, graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.\]). the following are exceptions to this criterion: patients with vitiligo or alopecia. patients with type i diabetes. patients with hypothyroidism (e.g., following hashimoto syndrome) stable on hormone replacement. any chronic skin condition that does not require systemic therapy. patients without active disease in the last 5 years may be included but only after consultation with the medical affairs team at the etop ibcsg partners foundation. patients with celiac disease controlled by diet alone. * uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease (ild), or serious chronic gastrointestinal conditions associated with diarrhoea. * psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring aes or compromise the ability of the patient to give written informed consent. * history of another primary malignancy except for: malignancy treated with curative-intent and with no known active disease 5 years before the first dose of durvalumab and of low potential risk for recurrence. adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease. adequately treated carcinoma in situ without evidence of disease. * history of leptomeningeal carcinomatosis. * history of active primary immunodeficiency. * active hepatitis infection, positive hepatitis c virus (hcv) antibody, hepatitis b virus (hbv) surface antigen (hbsag) or hbv core antibody (anti-hbc). participants with a past or resolved hbv infection (defined as the presence of anti-hbc and absence of hbsag) are eligible. participants positive for hcv antibody are only eligible if polymerase chain reaction is negative for hcv rna. * known hiv infection that is not well-controlled. all of the following criteria are required to define an hiv infection that is well controlled: undetectable viral rna load for 3 months, cd4+ count of 500 cell per mm3, no history of aids-defining opportunistic infection within the past 12 months, and stable for at least 3 months on the same anti-hiv medication. * current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. the following are exceptions to this criterion: intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection). systemic corticosteroids at physiologic doses not exceeding 10 mg/day of prednisone or its equivalent. steroids as premedication for hypersensitivity reactions (e.g., ct scan premedication). - receipt of live attenuated vaccine within 30 days prior to the first dose of durvalumab. note: patients in the adopt-lung trial, should not receive live vaccine whilst receiving durvalumab and for up to 30 days after the last dose. concurrent enrolment in another interventional clinical trial. * known allergy or suspected hypersensitivity to durvalumab or its excipients. * judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions, and requirements. * female patients who are pregnant or in the period of lactation. * female patients of childbearing potential and sexually active men who are not willing to use a highly effective contraceptive method during the trial until at least 90 days after the last dose of protocol treatment.
